Chelsea are unsure why attacking midfielder Mason Mount is the subject of transfer speculation.

Mount is an academy graduate and a key member of the team under coach Thomas Tuchel.

He was the supporters' player of the year last term, excelling under both Tuchel and Frank Lampard.

However, Mount has niggling issues this term, completing 90 minutes only five times this term.

According to The Athletic, club sources are mystified as to why Mount leaving is a creditable rumour in the media at present.

They believe that contract talks with Mount will conclude soon and very positively.

Real Madrid is one club who has been linked with the 22-year-old.
